SUPPLY-VALVE.

T all whom it may concern:

Be it known thatl, Gnouen F. VOIGT, a citizen of the United States, residing at Charlestown, in the county of Clark and State of Indiana,'have invented a new and useful Supply-Valve, of which the following is a specification.

The present invention relates toimprovements in a supply valve of the type generally used in flush tanks for water closets and the like, one object of the invention, being the-provision of a type of valve of this character, which when the float lowers due to the out-flow of water from the tank, the inlet valve controlled by the float will be locked infull open position until the float has reached approximately its full elevation, at which time the valve will be automatically released and thus fully closed so as to reduce the noise generally occasioned due to the gradual closing of the valve as the float elevates. k

A further object of the present invention, is the provision of a supply valve of this character, in Which the float controlled member is free to move upon its upward movement without affecting the valve, the valve being locked in full open position to be -re-' leased finally when the float has been elevated to its full height.

A still further object of the present invention, is the provision of a flushv valve of this character which is simple, inexpensive and durable in construction, and which is readily applied and put into use.

i/Vith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination and arrangement of parts andin the, details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment 01":

the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsFigure l is a vertical central sectional view through the complete valve structure showing the float carrying rod broken away to reduce the length thereof. Fig. 2 is a section taken on line 22 of Fig. 1. Fig. 3 is a partial view of the parts in the position they assume when the valve is locked in its open position just previous to the elevation of the float rod. Fig. 4 is Specification of Letters Patent. Patgntgd June 15 1915 3 Application filed November 20, 1914. Serial No. 873,197.

a top plan view of the parts shown in Fig. 3. Fig. 5 is a section on line 55 of Fig. 1.

Referring to the drawings, the numeral 1 designatesthe bottom portion of the tank in which is connected the coupling 2 into which the water is fed to the valve casing 3. Connected to and carried upwardly from the valve casing 3 is the stand pipe at, which is provided with the downwardly disposed outlet pipe 5. A guide (3 is disposed in the stand pipe 4 at a point adjacent the upper edge at the junction or" the pipe 5 with the stand pipe to form a guiding means for the valve stem 7 which carries upon its lower end, the ball valve 8 which is normally held upwardly by means of the water pressure from below upon the valve to thus hold the valve upon the valve seat 8 and prevent water from passing upwardly through the stand pipe and out of the outlet or discharge pipe 5.

The cylindrical member or guiding plunger 12 is threadedly connected to the upper end of the stem 7 as at 11. A vent 10 is provided in the guide 6, so that the plunger 12 will rapidly fall when the valve 8 is de pressed, and said vent prevents water hammering. Carried upon the upper end of the cylindrical member 12, is a stem 13 provided with the button or head 14, the same being disposed to receive the'projection 15 of the sleeve 16, which in turn carries the rod 19 actuated by the float 20. The sleeve 16 is fulcrumed by means of the pin 17 to the lug 18 which in turn is formed integral with the upper end of the stand pipe 1. It will thus be seenthat upon the lowering of the float 20, that the button lt will be engaged by the projection 15 and in turn the valve 8 will be lowered and thus permit water to flow upwardly and out of the discharge pipe 5. v

In order to provide a means for locking the valve in its lowermost or open position, apertured lugs 21 are formed upon the upper edge of the stand pipe 4: at a diametrically opposite point to the lugs 18 and between such lugs is pivoted a lever 22 which is provided with the bent end 23 for passing above and engaging the rod 19, the lower end 21 constituting a trigger for disposition above the upper end of the cylindrical member 12 when the same is in the lowermost position, as illustrated in Fig. 3, to thus lock the valve 8 in its position after the float 20 has lowered and pushed the valve in such position. WVhile the parts are in this position, it is evident that the Water entering the tank causes the float 20 to elevate and will consequently elevate the rods 19 and 22 to finally disengage the trigger 24% from the member 12 or from the position shown in Fig. 8 to that shown in Fig. 1, thus releasing the valve 8 which will be acted upon by the water pressure to engage the seat 8 and prevent theflow of water through the pipe 5 By this means, there is no gradual closing of the valve '8, but a sudden closing thereof, so that the water is permitted to run at full pressure into the tank up to the time it is cut off by the release of the member 12 thereof.

What is claimed is:

1. A. flushing valve, including a casing, a vertically movable valve mounted therein, a float actuated rod connected to the upper end of the casing and disposed to engage the upper end of the valve stem, and a lever pivoted to the upper end of the casing and acting as a lock for locking the valve stem and valve in lowermost and open position, the opposite end of said lever engaging at all times the float actuated rod whereby upon the lowering of the float rod and the opening of the valve, the valve is locked in such position until the float has been raised a predetermined distance at which time the valve is released.

2. A flushing valve, including a valve casing, a stand pipe having a downwardly disposedoutlet pipe connected to and in communication with the valve casing, a valve stem mounted for sliding movement within the stand pipe, a valve carried upon the lower end thereof, a cylindrical member carried upon the upper end of the stem at a point above the junction of the outlet pipe therewith, the upper end thereof being accessible through the upperend of the stand pipe, a float actuated rod pivoted to the upper end of the stand pipe and provided with means for engaging the upper end of the cylindrical member of the valve stem for depressing the same and opening the valve upon the lowering of thefloat, a lever pivoted intermediate of its ends to the upper end of the casing and at the side remote from the pivotal point of the float actuated rod,'one end thereof being projected in the path of the cylindrical member to engage the same when the float rod is lowered to lock the valve in open positiorn'and a hook upon the opposite end of the lever to engage the float actuated rod, whereby as the float ascends the cylindrical member and valve are.

released. 7 v

3. A flushing valve, including a valve casing, a stand pipe having a downwardly disposed outlet pipe connected to and in communication with the valve casing, a valve stem mounted for sliding movement within,

the stand pipe, a valvecarried upon the lower end thereof, a cylindrical member carried upon the upper end ofthe stem at a point above the junction of the, outlet pipe therewith, the upper end thereof being accessible through the upper endofvthe stand pipe, a floatactuated rod pivoted to the up per end of the stand pipe and provided'with means for engaging the upper end of the cylindrical member of the valve stem for depressing the same and opening the valve upon the lowering of the. float, a lever pivoted to the upper end of the stand pipe at V the opposite side to the float actuated rod and having one end in slidableengagement wlth the float actuated-rod, and a trigger upon the opposite end thereof disposed in C'opies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
